Abstract
The invention discloses a hydraulic shock absorber. The hydraulic shock absorber is characterized in that the shock absorber comprises a threaded connection rod (1), a limiting baffle (2), disk-shaped reinforcing rings (4), an inertia channel (5), a metal framework (6), a connecting base (7), main spring rubber bases (11) and main springs (12); the threaded connection rod (1) is fixedly arranged on the metal framework (6); the main springs (12) are arranged at the two sides of the metal framework (6) and are connected with the disk-shaped reinforcing rings (4) through the main spring rubber bases (11); the limiting baffle (2) is arranged below the metal framework (6); the disk-shaped reinforcing rings (4) are arranged at the two sides of the limiting baffle (2) and are fixedly clamped onto the connecting base (7); and the inertia channel (5) is arranged inside the limiting baffle (2).
Description
Technical field
The invention discloses a kind of damper, more particularly to a kind of hydraulic damper.
Background technology
Hydraulic damper is throughout adopting hydraulic damper in automotive suspension system.Its reason is, when vehicle frame and vehicle bridge make a return journey relative motion piston make a return journey in the cylinder barrel of damper move when, the fluid in damper housing just repeatedly from the inner chamber hole that some are narrow via process flows into an other inner chamber.Now, liquid just constitutes the resistance monk's power to vibrating with the friction of inwall and the internal friction of liquid one's share of expenses for a joint undertaking.A kind of shock damper that hydraulic damper has been grown up since being the sixties.Its layout characteristic is that equipped with a floating piston, the sealed gas chamber kind constituted in floating piston and cylinder barrel one end is filled with high pressure nitrogen in the bottom of cylinder barrel.The O-ring seal equipped with big cross section on floating piston, it thoroughly separates oil harmony.On thing piston equipped with its activity rate it is big and small and change channel cross-sectional area deflation valve and spread valve.When wheel bob, the thing piston of damper is made a return journey activity in fluid kind, and it is poor to make to occur between the epicoele and cavity of resorption of thing piston oil pressure, and pressure oil just pushes deflation valve open and spreads valve and movable back and forth.Because valve occurs larger resistance monk's power to pressure oil, vibration is set to decay.Existing hydraulic damper anti-corrosive properties are poor, and complex structure, sealing is poor, it is possible that the problems such as phenomenon of oil leak.
The content of the invention
It is good that the technical problem to be solved in the present invention there is provided a kind of antiseptic property, compact conformation, and in symmetrical structure, installing space is little, and stress is more reasonable, good airproof performance, is not in the hydraulic damper of the phenomenon of oil leak.
In order to solve above-mentioned technical problem, the present invention provides a kind of hydraulic damper, it is characterised in that：Including whorl brace rod, postive stop baffle, plate-like stiffening ring, inertia channel, metallic framework, connect base, rubber spring seat and main spring；The whorl brace rod is fixed on metallic framework, and the side of metallic framework two is equipped with main spring, and main spring is connected by rubber spring seat with plate-like stiffening ring；The metallic framework has postive stop baffle, and the side of postive stop baffle two is provided with plate-like stiffening ring, and plate-like stiffening ring is fixed and is connected in connect base；Inertia channel is provided with the postive stop baffle.
As a further improvement on the present invention, inertia channel body and lower inertia channel body are provided with the inertia channel.
As a further improvement on the present invention, it is provided with rubber membrane in the postive stop baffle.
As a further improvement on the present invention, the postive stop baffle has rubber counterdies.
Using said structure, its advantage is：Antiseptic property of the present invention is good, compact conformation, and in symmetrical structure, installing space is little, and stress is more reasonable, good airproof performance, many advantages, such as be not in the phenomenon of oil leak.
Description of the drawings
Fig. 1 is a kind of structural representation of hydraulic damper of the invention.
In figure：1- whorl brace rods（1）, 2- postive stop baffles, 3- rubber membranes, 4- plate-like stiffening rings, 5- inertia channels, 6- metallic frameworks, 7- connect bases, the upper inertia channel bodies of 8-, inertia channel body under 9-, 10- rubber counterdies, 11- rubber spring seats, the main springs of 12-.
Specific embodiment
Explanation that with reference to the accompanying drawings and examples the present invention will be further explained.
As shown in figure 1, a kind of hydraulic damper, it is characterised in that：Including whorl brace rod 1, postive stop baffle 2, plate-like stiffening ring 4, inertia channel 5, metallic framework 6, connect base 7, rubber spring seat 11 and main spring 12；The whorl brace rod 1 is fixed on metallic framework 6, and the side of metallic framework 6 two is equipped with main spring 12, and main spring 12 is connected by rubber spring seat 11 with plate-like stiffening ring 4；The metallic framework 6 has postive stop baffle 2, and the side of postive stop baffle 2 two is provided with plate-like stiffening ring 4, and plate-like stiffening ring 4 is fixed and is connected in connect base 7；Inertia channel 5 is provided with the postive stop baffle 2；Inertia channel body 8 and lower inertia channel body 9 are provided with the inertia channel 5；Rubber membrane 3 is provided with the postive stop baffle 2；The postive stop baffle 2 has rubber counterdies 10.
Main parts size of the present invention adopts austenitic stainless steel material, and anti-corrosive properties are good；Compact conformation, and in symmetrical structure, installing space is little, and stress is more reasonable；Damping force is big, and dynamic response time is short；The control resistance that rubs is little, the generally below 1%-2% of rated load；Head, afterbody is hinged and adopts oscillating bearing, it is allowed to which more most angle of oscillation is ± 6 °；Using special hydraulic oil and sealing medium, stable performance, sealing life is long；Can continuously work at a temperature of 93 DEG C, short-term operation stability is up to 148 DEG C.
Antiseptic property of the present invention is good, compact conformation, and in symmetrical structure, installing space is little, and stress is more reasonable, good airproof performance, many advantages, such as be not in the phenomenon of oil leak.
Any damper using designed by the technical characteristic similar with the present invention will fall under the scope of the present invention.
